While there’s been no suggestion that drugs or alcohol played a role in the incident, state Sen. Carl Kruger (D-Brooklyn) visited the school yesterday to say the school is troubled.

“Neighbors have complained about drinking and drug activity at the school for years,” said Kruger. “This tragedy highlights the need to improved security at the school.”

An Education Department source complained that Kruger “barged” into a meeting in the principal’s office and dropped off empty cans of alcohol he found. “Nothing was supposed to be touched as there is a police investigation going on, so he basically just tampered with evidence,” said the source.

Kruger said he saw no crime tape.

Education spokeswoman Margie Feinberg said guards watch over the school at night, adding: “The incident is under investigation, and the school is cooperating with police.”

Still don’t get why people are blaming the school when unauthorized people shouldn’t be climbing on scaffolding in the first place. The guards protect the building itself; that’s their job. THe scaffolding is separate and really, unless you have a circle of guards around the perimeter, you’re not going to get the whole place secure.
